In the form of a log of wood, Krishna is floating in the ocean of rādhā bhāva which is in the heart of Rādhārani...

"Radhe, Your love for Me is like a very deep ocean. And in order to reach such an ocean, and drown in that deep ocean, I have assumed this form, Jagannatha. In this form I will stay eternally in Sri Ksetra.”

This is Jagannatha-vigraha, rādhā viraha vidhura, Krishna feeling intense separation from Rādhā. In the form of a log of wood, He is floating in the ocean of Rādhā bhāva, which is in the heart of Rādhārani.

“And when I appear again as Caitanya Mahaprabhu, assuming Your sentiment and complexion, I will also stay in Jagannatha Puri Dhama.”
